ABSTRACT OF THE DISCLOSURE A printing calculating machine having aregister provided with a set of denominations exceeding the actuators isadapted to locate the register in an initial transverse position withsaid exceeding denominations at the right of the actuators and todisplace transversely the same under the control of a differentiallysettable stepped member to cause a predetermined number of saidexceeding denominations to cooperate with said actuators to accumulatetherein corresponding orders of an amount. A total taking device causesthe register to return to the initial position to cut off thedenominations of the total contained in the exceeding denominations ofsaid register, and an additional printing member prints saidpredetermined number of said exceeding denominations simultaneously withthe total.

The present invention relates to a printing calculating machinecomprising a plurality of denominationally arranged actuatorsdifferentially movable to represent an amount and associated with aplurality of printing members for printing said amount, and comprising atransversely movable register adapted to engage said actuators andhaving a set of denominations exceeding said plurality, a differentiallysettable member being provided for causing said register to betransversely moved to engage a predetermined number of said exceedingdenominations with said actuators.

There are known printing calculating machines of the above type whereinthe exceeding denominations are normally at left of the actuators, theregister being displaced rightwards in some specific cases for engagingthe exceeding denomination with the actuators. When the total is taken,the figures accumulated in said denominations are cut off, withouthaving any record thereof on the paper.

This and other disadvantages are obviated by the printing calculatingmachine according to the invention, which is characterized by anadditional printing member adapted to be conditioned by said settablemember for printing a figure corresponding to said predetermined membersimultaneously with the amount printed by said plurality of printingmembers.

General description The calculating machine comprises fifteen actuatorsformed of racks 15 (FIG. 1) differentially movably under the control ofa universal bar 16 through an advancing stroke (leftwards in FIG. 1) anda return stroke to represent an amount. The calculating machinecomprises also a first storing device formed of a set up carriage 17transversely slidable on a square shaft 18 rotatably mounted on themachine frame, and on a shaft 19 vertically movable on the same frame.The carriage 17 is provided with fifteen toothed sectors 21 rotatablyand slidably mounted on the shaft 19 and adapted to be differentiallyset up clockwise from the position zero indicated in FIG. 1 by a ten keykeyboard not shown in the drawings. A second storing device formed of asecond set up carriage 22, substantially symmetrical to the carriage 17with respect to the racks 15, is transversely slidable on a secondsquare shaft 23 rotatable on the machine frame, and on a verticallymovable shaft 24. The carriage 22 is provided with fifteen toothedsectors 26 rotatably and slidably mounted on the shaft 24 and adapted tobe differentially set up counterclockwise with respect to the zeroposition of FIG. 1, through the same ten key keyboard. The sectors 21 ofthe carriage 17 and the sectors 26 of the carriage 22 are normallyrotated according to the last amount set up thereon, in the mannerdescribed in the United States patent application No. 398,915, datedSept. 24, 1964, now Patent No. 3,319,882.

The calculating machine is provided with a cyclically operatingmechanism comprising three shafts 30', 31 and 32 (FIG. 6), substantiallydescribed in the United States patent application No. 506,958, datedNov. 9, 1965, now Patent No. 3,331,556. The shaft 30 is rotatedcounterclockwise one revolution at the depression of any function motorkey. Near the end of its cycle the shaft 30 starts the first part of anauxiliary cycle effected by the shaft 31 bodily rotated clockwise with asleeve 44. The shaft 31 and the sleeve 44 are stopped after beingrotated 270 degrees clockwise, while a cycle of the third shaft 32 isstarted to control the universal bar 16 of the racks 15 (FIG. 1),whereby the shaft 32 represents the main shaft of the machine. At theend of this cycle a second part of the auxiliary cycle is effected. Thewhole of one cycle of the shafts 30, 31 and 32 represents a machinecycle.

The calculating machine is also provided with la pro gram control devicecomprising a shaft 51 (FIG. 1) having a set of cams each one adapted tocontrol a function of the machine, substantially as described in theUnited States 'copending patent application Ser. No. 533,974, dated Mar.14, 1966, now patent No. 3,370,788, entitled: Program Control Device fora Calculating or Like Machine. Particularly the shaft 51 is adapted toassume a predetermined sequence of stations selected from a plurality oftwenty stations I, II, XX. The shaft 51 is selectively rotated under thecontrol of a cam of the sleeve 44, and predisposes some machinefunctions. For example the shaft 51 is provided with a pair of earns 54and 56 (FIG. 1) associated with the carriages 17 and 22 and each Oneadapted to control the transverse displacement of the correspondingcarriage. To this end the cam 54, through a lever 57 fulcrumed at 58, isadapted to locate a link 59 into three different angular positions. Thelink 59 is connected with a crank lever 61 secured to a square shaft 62slidably mounting a nack 63. The latter on one hand is provided with anotch engaged by a pro ection 64 of the carriage 17, on the other handit is adapted to engage a pinion 66 for being displaced leftwards, or apinion 67 for being displaced rightwards, or an arm 68 of a bail 69 forbeing transversely locked. The pinion 66 is secure-d to a longitudinalshaft 71 adapted to be rotated by a clutch not shown in the drawings,while the pinion 67 is secured to a second shaft 72 connected to theshaft 71 through a pair of pinions 73 to be rotated in an oppositedirection.

Similarly the cam 56 (FIG. 1) of the shaft 51, through a lever 77 alsofulcrumed at 58 is adapted to locate a second link 78 into threedifferent positions. The link 78 is connected with a crank lever 79secured to a square shaft 81 slidably mounting a second rack 82 engaginga projection 83 of the c-arirage 22. The rack 82 is adapted to engagethe pinion 67 for being displaced leftwards, or the pinion 66 for beingdisplaced rightwards, or another arm 84 of the bail 69 for beingtransversely locked. The carriages 17 and 22 are'drawn rightwards byindividual springs not shown in the drawings, which are normally withouteffect because one of the pinions 73 is locked by a latch 76.

Thereafter the links 59 and 76 predisposed by the corresponding cams 54and 56 are longitudinally displaced by two lugs 87 and 88 of a lever 89fulcrumed on a stationary shaft 91. The lever 89 is rocked clockwise atthe beginning of any cycle of the shaft 30, as well as in the first partof the auxiliary cycle before the program shaft 51 is displaced, wherebythe function predisposed by the program when it reaches a specificstation is actuated only in the following machine cycle.

Each one of the two carriages 17 and 22 is associated with a sector 92(FIG. 2), respectively 93, slidably mounted on a corresponding shaft311, respectively 312, but bodily rotatable therewith. Each sector 92,93 is urged leftwards by a compression spring 315 (FIG. 11) to contact aprojection 316 of a corresponding toothed bent edge 313, respectively314 (FIG. 2), of a slide 94 transversely slid-able on the shafts 311 and312. The slide 94 is provided with another toothed edge engaging apinion 96 synchronoulsy rotating with the shaft 71. The sectors 92 and93 are selected by a cam of the program shaft 51 and are operated forcontrolling the transverse displacement of the corresponding carirage,whereas their position on the slide 94 represents a record of the numberof denominations set up on the same carriage.

Furthermore, each sector 92, 93 is adapted to cooperate with acorresponding lug 317, 318 of a slide 319 slidably mounted on twostationary pins 320 (FIG. 11). The slide 319 is normally urgedrightwards by a spring 321 prevailing over the springs 315 and isprovided with a projection 322 adapted to cooperate with a bail 323fulcrumed on a vertical shaft 324. In turn the bail 323 may cooperatewith a clutch not shown in the drawings, which is adapted to be engagedby a cam of the shaft 30 (FIG. 6) and by a cam of the shaft 31 forrotating the shaft 71 and the pinion 96 (FIG. 11) to move the slide 94leftwards.

When one of the carriages Hand 22 is to be displaced leftwards, theabove clutch is engaged while the corresponding sector 92, 93 (FIG. isrocked at first counterclookwise for temporarily disengaging the toothededge 313, 314. Thereafter the sector 92, 93 is returned clockwise to anintermediate position so as to reengage the edge 313, 314 and to lie onthe horizontal plane of the lug 317, 318 of the slide 319. Now, when thesector 92, 93 encounters the corresponding lug 317, 318, the slide 319(FIG. 11) is displaced leftwards thus rocking the bail 323 clockwise,whereby the :above clutch is disengaged. The slide 319 may returnrightwards when the sector 92, 93 (FIG. 2) will be again disengaged fromthe toothed edge 313, 314.

Furthermore, the calculating machine comprises a rack (FIGS. 3 and 9)which will be called hereinafter capacity rack. The rack 115 is providedwith two arms 270 and 271 slidably mounted on a square shaft 116rotatably mounted on the machine frame. The rack 115 may alternatelyengage a pinion 117 of the shaft 72 for being displaced leftwards, or apinion 118 of the shaft 71 for being displaced rightwards, or aprojection 119 of the bail 69 for being transversely locked. The rack115 is normally urged rightwards by a spring 121 and engages the pinion117. The diameter of the pinions 117 and 118 is less than that of thepinions 66 and 67, whereby the rack 115 has a correspondingly min-orpitch.

Secured to the shaft 116 is an arm 122 (FIG. 3) pin and slot connectedwith a link 123 slidably mounted on a stationary pin 124. Furthermorethe link 123 is normally spring urged to contact a pin 125 of a lever126 fulcrumed at 58 and normally urged by a spring 127 to contact a cam128 of the program shaft 51. The link 123 is provided with twocomplementary stepped edges which may cooperate with the lugs 87 and 88of the lever 89.

The carriages 17 and 22 and the rack 115 (FIGS. 1 and 3) may be restoredrightwards by disengaging the latch 76 from the pinion 73, or by causinga cam of the sleeve 44 operating during the second part of the auxiliarycycle to disengage, under the control of the program shaft 51, the bail69 from the rack 115, 63 and 82. When the program shaft 51 is at rest,it normally predisposes the disengagement of the sole latch 76.

The calculating machine is provided with a printing device comprisingfifteen typewheels 129 (FIG. 2), each one connected to one of theactuators 15 by an intermediate lever 130. The levers 130 are controlledby a universal bar 131 carried by a pair of arms 132 fulcrumed at 133and rocked clockwise only in the printing cyles. The typewheels 129 areindividually mounted on a slide 120 having a project-ion 120' adapted tobe controlled by a zero printing control plate 107 in the mannerdescribed in the United States patent application No. 405,368, datedOct. 21, 1964, now patent No. 3,260,499. To this end, before printin anamount, the carriage 17 (FIG. 1) is displaced leftwards together withthe slide 94, till the plate 107, which is moved leftwards by the slide94, is placed at left of the highest denomination of the amount to beprinted. In this manner the carriage 17 is aligned with the amount to beprinted and, in the case a total is taken, said total is automaticallyback transferred to the carriage 17.

The calculating machine is provided with an automatic multiplicationdevice adapted to process the multiplier starting from the highestorder, substantially as described in the copending United States patentapplication Ser. No. 539,457, dated Apr. 1, 1966, entitled, AutomaticShortcut Multiplication Device for a Calculating Machine. Upon settingup the multiplicand into the carriage 17, a multiplication key isdepressed and on one hand it causes the multiplicand to be printed, onthe other it starts the program shaft 51 for a sequence of stationscomprising the stations VI, VII, XII and XIV. The program in the stationVI predisposes the carriage 22 for setting up the multiplier.

Then the carriage 22 is displaced leftwards step by step together withthe carriage 17 and the capacity rack 115, which is thus displacedleftwards as many steps as the sum of the denominations of themultiplicand and the multiplier.

Now a product key is depressed and under the control of the programcauses the carriage 22 to be returned rightwards. Thereafter the programpredisposes the carriage 22 for being displaced leftwards and thecarriage 17 forbeing displaced rightwards. Then, under the control ofthe program in the station VII, the sectors 26 are sequentially sensedby a sensing device comprising a support generically indicated by thenumeral 109, for controlling the number of cycles required by thecorresponding multiplier denomination.

The multiplier may be already stored in the carriage 22. In this casethe product key is depressed without setting up the multiplier throughthe keyboard. Then, before beginning the multiplication, under thecontrol of the program, the two carriages 17 and 22 are tabulatedleftwards through a number of steps equal to the number of thedenominations of the multiplier. The support 109 at the beginning of themultiplication is displaced leftwards and is then looked in an effectiveposition. Thereafter the carriage 22 is returned at right, while thesupport 109 is lowered for sequentially cooperating with the varioussectors 26 of the multiplier carriage 22.

For shifting from one denomination to the next lower one of themultiplier, the carriage 22 is displaced leftwands step by step, whilethe carriage 17 is returned rightwards step by step. When the carriage22 reaches the position it had immediately after the set up operation,the sector 93 (FIG. 2) causes the program shaft 51 to be displaced tothe station XII, wherein it causes the multiplier to be printed.Finally, the program in the station XIV causes the product to beprinted.

Furthermore, the calculating machine is provided with an automaticdivision device of the type described in the copending United Statespatent application Ser. No. 539,379, dated Apr. 1, 1966, entitled: TenKey Calculating Machine Adapted To Effect Multiplications as Well asDivisions. Upon setting up the dividend into the carriage 17, a divisionkey is depressed, which on one hand causes the dividend to be printed,and on the other hand starts the program shaft 51 for a sequence ofstations comprising the stations X, XIII, XV, XVI, XVII, XVIII and XIX.The program in the station X predisposes the carriage 22 for setting upthe divisor and the capacity rack 115 for being displaced leftwards.

Thereafter a quotient key is depressed and, under the control of theprogram in the station XIII, causes the divisor to be printed. Thenunder the control of the program in the station XV, the capacity rack115 is predisposed for being displaced leftwards and the divisor isautomatically aligned with the dividend, whereby the rack 115 isdisplaced leftwards a number of steps equal to the maximum number ofdenominations of the quotient. The carriage 17 is now returnedrightwards and under the control of the program in the station XVI it iscleared, while the carriage 22 and the rack 115 are predisposed forbeing returned right-wards.

Thereafter, under the control of the program in the station XVII, acounting member, generically indicate-d by the numeral 110, accumulatesthe quotient denominations digit by digit into the sectors 21 of thecarriage 17. For shifting from one denomination to the other of thequotient, the carriage 17 is displaced step by step leftwards, while thecarriage 22 and the rack 115 are returned step by step rightwards. Whenthe rack 115 is displaced behind its initial position, it causes theprogram shaft 51 to be displaced to the station XVIII, wherein thequotient is printed. Then the program is displaced to the station XIX,wherein the division remainder is printed.

Cut-ofi denominations from the product The racks may cooperate with aregister 135 of the type having two sets of intermeshing pinions.Particularly, the register 135 is provided with twenty pairs of pinions(FIG. 7), that is with five denominations 136 exceeding the capacity ofthe carriages 17 and 22 and the racks 15, substantially of the typedescribed in the copending United States patent application Ser. No.537,489, dated Mar. 25, 1966, now Patent No. 3,358,917, entitled TotalTaking Device for a Calculating or Like Machine, with reference to FIG.7 thereof. Since the denominations 136 may accumulate denominations of aproduct or a dividend to be cut off, they will be hereinafter called cutoff denominations. The pinions of the register 135 are rotatably mountedon a pair of shafts 137 carried by two flanks 138 and 139, each onesecured to a shaft 141, respectively 142. The shafts 141 and 142 arerotatably and slidably mounted on two plates 143 transverselystationary, but adapted to be vertically displaced for engaging theregister with the racks 15. Normally the register 135 is located in theposition of FIG. 7, wherein the five cut off denominations 136 are atright of the racks 15.

The shaft 141 is provided with two flanges 144, cooperating with aroller 146 of a lever 147 fulcrumed on a shaft 148 rotatably mounted onthe machine frame. Secured to the shaft 148 are also two oppositetoothed sectors 149 and 151 engaging two vertical slides 152 and 153vertically slidable on two stationary pins 154. The two slides 152 and153 are provided with two opposite stepped edges 156, respectively 157,adapted to cooperate with a lug 158 of a slide 159. This latter ishorizontally slidable on two pins 161 secured to a lug 162 of a verticallink 163 slidably mounted on a stationary pin 164 (FIG. 6). The link1-63 is also linked at 166 with a lever 167 pivoted at 168 andcooperating with a pair of complementary cams 169 of the sleeve 44.

The slide 159 is provided with another lug 171 engaging a forked arm ofa horizontal lever 172 (FIG. 8) fulcrumed on a stationary pivot 173. Asecond forked arm of the lever 172 engages a lug 174 of a lever 176(FIG. 6) fulcrumed on a stationary pivot 177. The lever 176 is providedwith a shoulder 178 adapted to cooperate with the upper end of a slide179 slidably mounted on two stationary pins 181. The slide 184 isprovided with a pin 182 cooperating with a tapered slot 183 of ahorizontal slide 184, which is adapted to be displaced forwards at thedepression of a total key in a known manner. Furthermore the lever 176is linked at 186 with a link 187 connected at 188 with a lever 189fulcrumed on a stationary pivot 191. The lever 189 is normally urged bya spring 192 to contact cam 193 of the shaft 30.

The link 187 is provided with a slot 194 engaged by a pin 196 of a bail197 (FIG. 4) fulcrumed on a pivot 198. The transverse portion of thebail 197 is engaged by a notch 199 of a sensing member formed of a bail200 (see also FIG. 7) rotatably and slidably mounted on the pivot 198.The bail 200 is provided with a lug 201 normally located above both astepped edge 202 of a stationary plate 203 and a first stepped edge 204(FIG. 5) of a differentially settable member or slide 206 (FIG. 4)slidably mounted on two stationary pins 208 and 209.

Located at right of the slide 206 (FIG. 7) and distanced therefrom twicethe distance between the slide 206 and the plate 203 is a secondstationary plate 211 (FIG. 6) adapted to cooperate with the lug 201(FIG. 7) when the bail 200 is displaced at right of the slide 206. Tothis end the bail 200 is provided with a projection 212 having a notchengaged by a bar 213 carried by two arms 214 and 216 secured to alongitudinal shaft 217 rotatably mounted on the machine frame. The arm216 is connected through a link 218 (FIG. 5) with a lever 219 fulcrumedat 221. Linked with the lever 219 is a link 222 pin and slot connectedwith a lever 223 fulcrumed at 58 and normally urged by a spring 224 tocontact a cam 226 of the program shaft 51. The link 222 is provided withtwo complementary stepped edges 227 adapted to cooperate with a pair oflugs 87' and 88 of a second lever 89 fulcrumed on the shaft 91 andmovable simultaneously with the lever 89 (FIG. 1) in a manner known perse.

The slide 206 is provided with an element or shoulder 228 adapted to befrontally engaged by the lug 201 of the bail 200. The forward end of theslide 206 is provided with a toothed portion 232 engaging a pinion 233rotatably mounted on a stationary shaft 234. The pinion 233 is axiallyprovided with a tooth 236 (FIG. 8) adapted to cooperate with a tooth 237of a second pinion 238 secured to a manipulative knob 239 rotatablymounted on the shaft 234. The pinion 238 cooperates with a spring 7urged locking member 241 (FIG. the action of which prevails over thespring 231. The cylindrical surface of the knob 239 (FIG. 8) is providedwith a scale indicating the number of denominations the register is tobe displaced.

Furthermore, the slide 206 (FIG. 5) is provided with a toothed edge 242adapted to be engaged by a lug 243 of a lever 244 fulcrumed at 246 andprovided with a pin 247 cooperating with a cam slot 248 of the lever219. Finally, the slide 206 is provided with a second stepped edge 249(FIG. 4) adapted to be sensed by a lug 251 of a bail 252 fulcrumed on astationary shaft 253. Another arm 254 of the bail 252 is normally urgedby a spring 256 to contact a pin 257 secured to one of the two lugs 132of the universal bar 131. Linked with the arm 254 is also a rack '8engaging an additional printing member or typewheel 259 similar to thetypewheels 129 (FIG. 2) and provided with numerical characters from zeroto five differently shaped with respect to the figures of the typwheels129, for example leaned towards the left (FIG. 4). The typwheel 259 iscarried by a slide 260 located at left of the slide of the typewheels129* (see also FIG. 7) and not provided with the projection 120'cooperating with the zero printing control plate 107. The slide 260 isprovided with a bent lug 261 adapted to selectively cooperate with aprinting control member formed of a lever 263 fulcrumed at 264 andhaving a pair of lugs 262 and 262 mutually distanced by a gap 269. Thelever 263 is normally urged by a spring 266 to contact a lever 267 (FIG.7) fulcrumed at 268 and connected through a link 270 with an arm 271secured to the shaft 217.

Normally the knob 239 is located at its zero position as shown in FIG.8, whereby the slide 206 is located in the longitudinal position of FIG.5. Then the lug 201 in sensing the stepped edge 204 is not affectedthereby, whereas the lever 263 (FIG. 4) through its lug 262 locks theslide 260, thus preventing the typewheel 25 from the printing.

Assuming that a multiplication is to be effected, the product of whichis requested to have a predetermined number of denominations cut off,for example two denominations at right of a decimal point, beforestarting the multiplication the number of denominations to be cut off isset up by manually rotating the knob 239 (FIG. 5) clockwise two steps.The knob 239 through the tooth 237 of the pinion 238 rotates the pinion233, which in turn displaces the slide 206 rearwards two steps. Duringthe cycle wherein the multiplicand is printed, and in all the cycleseffected in a station of the program wherein the cam 226 holds the link222 in the position of FIG. 5, the register 135 is not displaced becausethe lug 201 (FIGS. 4 and 7) of the bail 200 senses the toothed edge 202of the stationary plate 203 and is immediately arrested thereby.Furthermore, the lug 262 of the lever-263 still prevents the typewheel259 from printing.

After having set up the multiplicand and the multiplier, when theprogram shaft 51 is located in the station VII, the cam 226 predisposesthe link 222 in its central position. During the cycle of the shaftwhich precedes the counting cycles of the shaft 32 corresponding to thefirst denomination of the multiplier, the lever 89' is rocked clockwiseand displaces the link 222 rearwards, thus rocking the lever 219counterclockwise. Then the cam slot 248 rocks the lever 244, the lug 243of which engages the toothed edge 242, thus positively locking the slide206 in the reached position. An accidental rotation of the knob 239during the multiplication is thus prevented.

Furthermore, the lever 219 through the link 218 rocks the arm 216 (FIG.7) counterclockwise bodily with the shaft 217, the arm 214 and the bar213. This latter displaces the bail 200 rightwards and removes the lug201 from the stationary plate 203, whereby the lug 201 may sense onlythe slide 206. The arm 271 is also rocked bodily with the shaft 217 and,through the link 270 and 8 the lever 267, rocks the lever 263 (FIG. 4)counterclockwise to' locate the gap 269 into the path of the lug 261thus releasing the slide 260.

Thereafter, the cam 193 (FIG. 6) of the shaft 30 causes the spring 192to rock the lever 189 clockwise. The lever 189 through the link 187 andthe pin 196 rocks the bail 197 (FIG. 4) counterclockwise together withthe bail 200. The lug 201 after being rocked two steps is now arrestedby the stepped edge 204 (FIG. 5) of the slide 206. Therefore, throughthe bail 197 and the slide 187 (FIG. 6), the lever 174 is rotatedcounterclockwise two steps. In turn the lever 172 (FIG. 8), displacesthe slide 159 leftwards two steps.

During the first part of the following auxiliary cycle of the shaft 31(FIG. 6) and of the sleeve 44, the cams 169 rock the lever 167clockwise. Then the slide 163, through the pins 161 (FIG. 7) lowers theslide 159, the lug 158 of which engages the two complementary steppededges 156 and 157 of the slides 152 and 153. These latter now throughthe sectors 149 and 151 and the shaft 148, rock the lever 147 clockwise,thus displacing the register leftwards two steps. The first two out offdenominations 136 Of the register 135 are thus located in correspondencewith the racks 15, whereby the two lowest denominations of the productwill be accumulated into the denominations 136.

At the end of the counting cycles of the multiplication, the programshaft 51 (FIG. 5) is displaced to the station XII to control theprinting of the multiplier. Thus the cam 226 through the lever 223additionally displaces the link 222 downwards. In the cycle of the shaft30 preceding the printing of the multiplier, the lever 89 through thelink 222 rocks the lever 219 additionally counterclockwise. Now the slot248 no longer displaces the lever 244 which still locks the slide 206.On the contrary, the link 218 through the arm 216 (FIG. 7), the shaft217, the link 270 and the lever 267, additionally rocks the lever 263(FIG. 4), thus locating the lug 262' into the path of the lug 261.Furthermore the bar 213, which is rocked counterclockwise bodily withthe arms 214 and 216 (FIG. 7), additionally displaces the bail 200rightwards, thus locating the lug 201 at right of the slide 206 andabove the stationary plate 211.

Thereafter, the cam 193 (FIG. 6) of the shaft 30, through the lever 189,the link 187 and the bail 197 (FIG. 4) causes the bail 200 to sense thestationary plate 211 (FIG. 7). Now this latter immediately arrests thelug 201 of the bail 200, whereby the slide 159 remains in the positionof FIG. 7. Then, the cams 169 (FIG. 6) of the sleeve 44, through thelever 16-7 and the slide 163 lower the slide 159. The lug 158 (FIG. 7)of the slide 159 through the plates 152 and 153, the sectors 149 and151, and the lever 147, returns the register 135 to the right hand endposition, whereby the cut off denominations 136 are returned at right ofthe racks 15. Simultaneously the program shaft 51 is displaced to thestation XIV.

During the subsequent cycle of the main shaft 32 wherein the multiplieris printed, the arms 132 (FIG. 4) of the universal bar 131 are rockedclockwise and the pin 257 releases the arm 254 of the bail 252. Then thelug 251 of the bail 252 senses the stepped edge 249 of the slide 206,thus causing the rack 258 to position the typewheel 259 for printing thefigure 2. The lug 262 however still pre vents the typewheel 259 fromprinting.

Furthermore during this cycle, which is a non-print cycle, the cut oil?denominations 136' are zeroized in the manner described in the citedPatent No. 3,358,917 entitled Total Taking Device for a Calculating orLike Machine, whereby the slide 184 (FIG. 6) has been displaced forwardsby the automatic depression of the corresponding total taking key, whichwas effected at the beginning of the cycle of the shaft 30. Then theslot 183 of the slide 184 raises the slide 179 which is brought into thepath of the shoulder 178 of the lever 176. The bail 200 (FIG. 4) is thusprevented by the slide 179 from sensing the slide 206 both in this andin the following machine cycle. In the cycle of the shaft 30, relatingto the following machine cycle, the lever 89' (FIG. returns the lever219, and therefore the bail 200 (FIG. 7) and the lever 263 (FIG. 4),into their intermediate position. Since the bail 200 is prevented by theslide 179 (FIG. 6) from sensing the stepped edge 204 (FIG. 4) of theslide 206, the register 135 remains in the right hand position.

During the cycle of the shaft 32 the product is finally printed, the twolowest denominations of which have been cut off. Therefore, the arms 132are rocked clockwise again and enable the bail 252 to sense again thestepped edge 249. Now the bail 252 predisposes the typewheel 259according to the figure 2, which is printed at left of the product, toindicate the number of cut 01f denominations which in this case is equalto the number of steps effected by the register 135 for accumulating theproduct.

Extended multiplication The calculating machine is adapted to effectmultiplications the product of which exceeds the capacity of theactuators. Such multiplication will be called Extended multiplication.To this end the arm 270 (FIG. 9) of the capacity rack 115 is providedwith a projection 272 normally urged by the spring 121 to contact an arm273 of a slide 274 transversely slidable on a shaft 276 and on astationary pivot 277. Furthermore, the slide 274 is provided with asecond arm 278 distanced from the arm 270 fifteen steps of the rack 115.A lug 279 (FIG. 5) of the arm 278 engages a forked arm of a lever 281(FIG. 8) fulcrumed at 282 and engaging with a second forked arm a lug283 of a member automatically movable from a rest position and formed ofa longitudinal slide 284 (FIG. 4). This latter is slidably mounted on apair of pins 286 and carries the pivot 198 of the bail 200. Furthermore,the slide 274 (FIG. 9) is provided with a tapered shoulder 287 adaptedto engage a pin 288 of a lever 289 fulcrumed on the pivot 277 andconnected through a rod 292 with a lever 293. This latter is fulcrumedon a pivot 294 and is adapted to engage a shoulder 296 of the link 59(FIG. 1).

The capacity rack 115 (FIG. 9) engages the pinion 117 when themultiplicand is set up, as well as when the multiplier is set up,whereby the rack 115 is displaced leftwards as many steps as the sum ofthe number of denominations of the multiplicand and the multiplier. Ifthis sum is comprised between fifteen and twenty, the product overcomesthe capacity of the racks 15 (FIG. 7), but does not overcome thecapacity of the register 135. Then the multiplication is effected byautomatically causing the cut off denominations 136 of the register 135to accumulate the denominations of the products exceeding the capacityof the racks 15.

In fact, when the rack 115 (FIG. 9) has been displaced fifteen stepsleftwards, the projection 272 of the arm 270 engages the arm 278 of theslide 274. Now, if the rack 115 is additionally displaced leftwards, theslide 274 is displaced leftwards as well and, through the shoulder 287,the lever 289, the rod 292 and the lever 293, predisposes the link 59 inits central position. Furthermore the slide 274, through the lever 281,displaces the slide 284 (FIG. 4) rearwards, together with the pivot 198,the bail 197 and the bail 200. Thus the lug 201 of the bail 200 engagesthe shoulder 218 of the slide 206, which is displaced rearwards as manysteps as the denominations of the product exceeding the capacity of theracks 15.

In the station VII of the program, during the cycle of the shaft 30concerning the first denomination of the multiplier, due to the positionof the link 59, the rack 63 (FIG. 1) is engaged with the arm 68 of thebail 69, instead of the pinion 67, while the slide 206 (FIG. 5) islocked in the reached position by the lever 244. Now, during the step bystep displacements of the carriage 22, the rack 115 (FIG. 9), the slide284 (FIG. 4) and the bail 200 are returned rearwards step by step.Therefore 10 in the cycle of the shaft 30 concerning eachfollowingdenomination of the multiplier, the lug 201 of the bail 200 senses thestepped edge 204 of the slide 206 and displaces the register 135 (FIG.7) leftwards step by step, while the carriage 17 remains at its extremeleftward position.

When the bail 200 (FIG. 4), and therefore also the slide 284, arerestored forwards, the bail 200 causes the register 135 (FIG. 7) to beno more displaced. In turn, when the slide 274 (FIG. 9) is restored, theshoulder 287 releases the pin 286, whereby the link 59 (FIG. 1) returnsto the lower position. Then the rack 63 engages the pinion 67 and isthus predisposed for being displaced rightwards step by step. Themultiplications will be completed in a manner similar to that abovedescribed with reference to the case wherein the slide 206 (FIG. 5) ismanually set up for cutting off of a number of denominations of theproduct equal to the denominations now exceeding the capacity of theracks 15. Therefore the product will be printed with said denominationscut off, while the typewheel 259 (FIG. 4) will print a figure equal tothe number of denominations cut off at right of the product in themanner above described.

According to a modified form of the invention, the typewheel 259 (FIG.10) is provided with a further character 5, whereas the slide 206 isprovided with an edge 326 distanced two steps from the highest step ofthe stepped edge 249. A further settable member or slide 328 is providedwith a projection 327 normally located into the path of the lug 251 andadapted to arrest the lug 251 one step higher than the highest step ofthe edge 249. The slide 328 is provided with a window 329 having aW-shaped edge urged by a spring 330 to cooperate with the pin 208.Furthermore the slide 328 is slidably mounted on a stationary shaft 329and is provided with a pair of engageable elements or shoulders 331 and332 adapted to cooperate with a corresponding pair of counterelements orlugs 333 and 334 of a lever 336. This latter is secured to a sleeve 337(FIG. 11) rotatably and slidably mounted on the shaft 329. Furthermore,secured to the sleeve 337 is an arm 338 normally urged by a spring 339to contact the projection 322 of the slide 319. Normally the lug 334 ofthe lever 336 is on the plane of the slide 328, whereas the lug 333 islocated on the right of the slide 328.

Furthermore, secured to the lever 336 is a pin 341 cooperating with anotch of a slide 342 (FIG. 10) slidably mounted on a stationary pin 343and urged by a spring 344 to contact this pin. The slide 342 is alsoprovided with a notch engaged by an arm 346 (FIG. 11) of a bail 347f-ulcrumed on a vertical shaft 348. A second arm 349 of the bail 347 isnormally located in the transverse path of a projection 351 of themultiplication cycle counting support 109.

Secured to the arm 270 of the capacity rack is a pin 352 adapted toengage a lug 353 of a lever 354, when the rack 115 is displacedleftwards fifteen steps. The lever 354 is fulcrumed at 356 and isnormally urged by a spring 357 to contact a stationary stop 358. Asecond stationary stop 359 is adapted to limit the clockwise rotation ofthe lever 354. This latter is also connected through a link 361 to abail 362 fulcrumed on a stationary shaft 363 and provided with a pin 364adapted to cooperate with the bail 323.

As it has already been mentioned, before the beginning of themultiplication the carriage 22 is displaced leftwards according to thenumber of denominations of the multiplier. Then generally the sector 93(FIG. 10) contacts the lug 318 of the slide 319, which thus holds thebail 323 (FIG. 11) rocked clockwise, and the arm 338, together with thesleeve 337 and the lever 336, displaced leftwards in the position shownby broken lines in FIG. 1 1.

Now, when the support 109 is displaced leftwards, the projection 351rocks the bail 347 clockwise, thus displacing the slide 342 rearwards.This latter through the pin 341 rocks the lever 336 (FIG.counterclockwise, but if the slide 328 is already displaced forwards asshown in FIG. 10, the lever 336 has no effect on the slide 328.Thereafter the support 109 is lowered and the projection 351 releasesthe bail 347 which is restored bodily with the slide 342 by the spring344, whereby the slide 342 will not be further affected till thebeginning of the next multiplication. Then the lever 336 is angularlyrestored, while after the first denomination of the multiplier has beenprocessed, the slide 94 returning rightwards together with the sector93, causes the slide 319 (FIG. 11) to be trans versely restored togetherwith the lever 336.

If the product exceeds the capacity of the racks (FIG. 7), but not thecapacity of the register 135, the carriage 17 is displaced leftwardsonly fifteen steps and is aligned with the highest denomination of theracks 15. The slide 94 (FIG. 10), through the sector 93 and the slide319, predisposes the lever 336 into the position shown in FIG. 1 bybroken lines as in the preceding case. In the case the slide 206 isdisplaced leftwards five steps, when the product is printed, the bail252 is arrested by the projection 327 and predisposes the typewheel 259for printing the figure 5.

Now, it is assumed that the multiplier is already set up on the carriage22 and that the multiplicand set up is such as the product exceeds thecapacity of the register 135 (FIG. 7). When the two carriages 17 and 22(FIG. 11) are tabulated leftwards, the rack 115, upon being displacedtwenty steps thus reaching the position corresponding to the maximumcapacity of the register, engages with the pin 352 the lug 353, Then thelever 354 is rocked clockwise and, through the link 361, the bail 362,and the pin 364, rocks the bail 323 clockwise, thus disengaging theclutch of the shaft 71, whereby the slide 94 is arrested. Then thesector 93 (FIG. 10) does not reach the lug 318 of the slide 319, whichremains in the position of FIG. 11 together with the arm 338 and thelever 336. In turn the rearward displacement of the bail 200 (FIG. 10)and of the slide 206 is stopped together with the displacement of therack 115 (FIG. 11).

Now, when the support 109 is displaced leftwards, the projection 351,through the bail 347 and the slide 342, rocks the lever 336 (FIG. 10)counterclockwise. Then the lug 334 of the lever 336 engages the shoulder332 and displaces the slide 328 rearwards thus locating the projection327 out of the path of the lug 251. Now the multiplication is effectedas in the preceding case, whereby the register 135 (FIG. 7) is firstlydisplaced leftwards step by step till its left hand extreme position,that is through five steps. Thereafter the carriage 17 (FIG. 11) beginsto be displaced rightwards.

The only difference with the preceding case is due to the fact that,when the lowest denomination set up on the carriage 17 is aligned withthe rack 15 of the lowest denomination, the multiplier is not exhausted.Then the multiplication is extended by additionally displacing thecarriage 17 rightwards step by step to process the exceedingdenominations of the multiplier, the lower denominations of themultiplicand being progressively excluded. Then, when the product isprinted, the lug 251 (FIG. 10) of the bail 252 is arrested by the edge326 of the slide 206 so predisposing the wheel 259 in correspondence tothe character 5, whereby a record is made of the fact that the productexceeds the register capacity and that the cut off denominations aremore than five.

The slide 328 may be restored forwards only at the beginning of amultiplication, the product of which does not exceed the registercapacity. In fact then, when the support 109 rocks the lever 336clockwise, the slide 319 (FIG. 11) displaces the lever 336 leftwards,whereby the lug 333 engages the shoulder 331 (FIG. 10) and displaces theslide 328 forwards.

Decimal point in the quotient The slide 206 (FIG. 5) is provided withanother toothed edge 297 engaging a pinion 298 secured to the shaft 276,which is rotatably mounted on the machine frame. Furthermore, slidablyand rotatably mounted on the shaft 276 is a stepped member or drum 300(FIG. 8) normally urged leftwards by a compression spring 301 andadapted to cooperate with a lug 302 of the arm 271 of the capacity rack115. The right end of the rack (FIG. 9) is provided with a tapered edge303 adapted to engage a shoulder 304 of the link 78.

The drum 300 (FIG. 8) is normally contacted by a lever 306 fulcrumed at307 and urged counterclockwise by a spring 308. The lever 306 whenrocked clockwise causes the division to be stopped in the mannerdescribed in the cited patent application Ser. No. 539,379 entitled: TenKeg Calculating Machine Adapted To Effect Multiplications as Well asDivisions.

Furthermore, the lever 306 may be engaged by an end of a slide 372slidably mounted on a stationary pin 373 and connected with a bail 374fulcrumed at 375 and normally urged by a spring 376 to contact astationary stop 377. An arm 378 of the bail 374 is adapted to be engagedby the left end of the carriage 17 upon being displaced leftwardsfifteen steps and therefore at the end of its leftward stroke. The slide284 (FIG. 4) is provided with a lug 307 adapted to cooperate with aprojection 308 of another slide 309 slidably mounted on the pins 208 and209 and normally urged by a spring 310 to contact the pin 209. The slide309 is provided with a stepped edge 379 opposite to the stepped edge 249of the slide 206 and adapted to be sensed by the same lug 251 of thebail 252, but normally out of the path thereof, If the knob 239 islocated in the zero position as in FIG. 5, on one hand the slide 206does not cause the register to be displaced, on the other hand thestepped drum 300 remains in the position of FIG. 8 and operates thelever 306 to stop the division when the capacity rack 115 is displacedrightwards one step from the position of FIG. 8, whereby the division isstopped at the end of the accumulation of the lowest whole denominationof the quotient.

Now assuming that a quotient is required with a predetermined number ofdecimal denominations, for example three denominations at right of thedecimal point, before starting the division the knob 239 is rotatedclockwise three steps from the position of FIG. 5. Then the knob 239displaces the slide 206 rearwards three steps, whereby the pinion 298through the shaft 276 rotates the stepped drum 300 clockwise threesteps. Now the lug 302 (FIG. 8) of the capacity rack 115 must bedisplaced rightwards four steps besides the rest position beforedisplacing the drum 300 leftwards to rock the lever 306, whereby threeadditional denominations of the quotient will be accumulated in thecarriage 17.

During the cycles wherein the dividend and the divisor are printed, thecam 226 (FIG. 5) of the program shaft 51 holds the link 222 in theposition of FIG. 5, whereby the stationary plate 203 does not allow thelug 251 to displace the register leftwards, whereas the typewheel 259(FIG. 4) is prevented from printing. The link 222 (FIG. 5) is notdisplaced even when the program shaft 51 is located in the stations XV,XVI and XVII in order to accumulate the quotient. As already mentioned,when the program shaft 51 is located in the station XVII, the carriage22 is displaced rightwards step by step together with the capacity rack115. When this latter is restored to the position shown in FIG. 9 inorder to accumulate the lowest whole denomination of the quotient, theprojection 272 of its arm 270 contacts again the arm 273 of the slide274, while the tapered edge 303 engages the shoulder 304 and locates thelink 78 (FIG. 1) in the central position, whereby the rack 82 willengage the arm 84 of the bail 69.

At the beginning of the following cycle of the shaft 30, the rack 115 isdisplaced one step rightwards, while the carriage 22 remains in thereached position that is with all the denominations of the divisor incorrespondence with the racks 15. Now, since the rack 115 (FIG. 9) notyet engages the stepped drum 300, this latter does not stop thedivision, but the arm 270 (FIG. 8) of the rack 115, through the slide274 and the lever 281, displaces the slide 284 (FIG. 4) forwardstogether with the pivot 198, the bail 197 and the bail 200. Now duringthe cycle of the shaft 30, the lug 201 senses the first step of thestepped edge 202 of the stationary plate 203 and predisposes the slide159 (FIG. 7) for displacing the register 135 leftwards one step. In thismanner the dividend-divisor shift required for accumulating the nextdenomination of the quotient, that is the first decimal denomination ofthe quotient, is effected by displacing the register 135 leftwardsinstead of displacing the carriage 22 rightwards.

Similarly, at each further rightward step of the rack 115 (FIG. '9), thebail 200 is displaced one step forwards to cause the register 135 to bedisplaced one step leftwards. When the lug 302 of the rack 115encounters the stepped drum 300, rocking the lever 306, it causes theprogram shaft 51 to be displaced to the station XVIII, wherein thequotient is printed. In this station the cam 226 (FIG. 5) predisposesthe link 222 in the central position, whereby the bail 200 (FIG. 7)locates the lug 201 above the slide 206, and the lever 263 (FIG. 4)locates the gap 269 into the path of the lug 261.

Since the slide 206 is displaced forwards three steps, during the cyclewherein the quotient is printed, the bail 252 upon sensing the steppededge 249 locates the typewheel 259 in correspondence with the figure 3,which is then printed at left of the quotient. Simultaneously the cutoff denominations 136 (FIG. 7) are zeroized as in the case of the cyclewherein the multiplier is printed, whereby the slide 184 (FIG. 6)locates the slide 179 into the path of the shoulder 178 of the lever176, while the program shaft 51 is displaced to the station XIX. Sincethe cam 226 (FIG. 5) of the program shaft 51 in the station XIX returnsthe link 222 in the position of FIG. 5, in the following remainderprinting cycle, the lug 262 (FIG. 4) of the lever 263 prevents theprinting operation of the typewheel 259, while the slide 179 (FIG. 6)prevents the lever 176 from being rocked, whereby the register 135 isrestored rightwards.

If the sum of the whole denominations of the quotient and of therequired decimal denominations is higher than fifteen, that is itexceeds the capacity of the carriage 17 (FIG. 8) of the quotient, thecarriage 17 upon being displaced through fifteen steps engages the bail374, which is rocked counterclockwise and displaces the slide 372rightwards, thus rocking the lever 306 clockwise to stop the division.In the quotient printing cycle the lug 251 (FIG. 4) is now arrested bythe stepped edge 379 after a number of steps equal to the steps effectedby the slide 284. Therefore, now the typewheel 259 prints a figureindicating the number of the decimal denominations of the quotienteffectively accumulated, instead of the lfigure corresponding to thedecimal denominations set up on the knob 239.

Percentage calculating device The pinion 233 (FIGS. 5 and 8) is integralwith a second pinion 380 engaging a toothed sector 381 fulcrumed at 382.The sector 381 is provided with an arm 383 (FIG. 5) cooperating with apin 385 secured to a key 384 for calculating the percentage,substantially of the. type described in the cited Patent No. 3,370,788entitled Program Control Device for a Calculating or Like Machinereference to the key there indicated by the numeral When the key 384 isdepressed, through the sector 381 the pinion 380 is rotated clockwisefour steps from the position of FIG. 5, together with the pinion 232independently from the position of the knob 239, whereby the slide 205is displaced rearwards four steps. If a percentage uplift or apercentage discount is to be calculated, the rate,

which generally is given with two denominations at right of the decimalpoint, is set up as a multipler. Then the displacement of the slide 206causes four denominations to be cut off from the product, which thuspresents the amount of the required uplift or the increasing or therequired discount.

On the contrary if the rate is to be calculated according to the formulaaib b the slide 206 upon being displaced four steps causes the quotientto be calcuated with four denominations at right of the, decimal point.Said quotient represents the value of the rate percent with twodenominations at right of the decimal points It is intended that manychanges, improvements and additions of parts may be made to thedescribed calculating machines without departing from the scope of theinvention, as claimed in the appended claims.
